4 Pack Slim Ice Packs for Lunch Boxes, Reusable Kids Cold Packs for Coolers

Product Information

About this item

• STAYS COLD UP TO 12 HOURS: Freeze for 8 hours to unlock up to 12 hours of max cold retention. Each lunch box ice pack uses a dense cold-retention gel that holds temperature through a full school day, work shift, or commute. Lunch ice packs that last — no refreezing mid-day.
• SEALED TIGHT, NO LEAKS: Double-sealed edges and a puncture-resistant outer shell keep the gel inside where it belongs — even after hundreds of freezes and thaws. These lunch bag ice packs won't split, seep, or soak your food bag. Wipe clean with a damp cloth after lunch.
• SLIM FIT FOR EVERY LUNCH BOX: At 4.5 x 6 inches and under half an inch thick, you get more room for food and less bulk in the bag. Thin ice packs for lunch box shapes, bento boxes, divided containers, and standard insulated totes. The flat ice packs come in 4 bold colorful designs and stack easy in the freezer for daily rotation.
• FOOD-SAFE FOR DAILY USE: BPA-free, phthalate-free, and non-toxic — safe to rest right against sandwiches, fruit, and snacks. Small ice packs built for lunch boxes, not cooler packs shrunk to fit. Works for kids ice packs for lunch box meals and adult work lunches alike.
• 4 PACK FOR EVERY LUNCH: Always have a cold pack ready — grab one from the freezer while yesterday's goes back in to refreeze. Four reusable freezer packs keep the rotation easy, and doubling up 2 cold packs for lunch box cooling adds extra cold on hot days or long trips.
